  1. 1. Explosionsrisker med metalldamm

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Stina Dufva; Anton Fast; [2018]
    Nyckelord :Dammexplosion; metall; pulver; aluminium; damm; processindustri; Technology and Engineering;

    Sammanfattning : Dust explosions in the process industry can have devastating consequences. The purpose of this work was to study the risks of dust explosions with metal dusts. It was also to provide an overview of the state of knowledge supplemented with laboratory scale experiments for different materials mainly to gain an understanding of the basic mechanisms. LÄS MER

  2. 2. Inductive heating of exhaust aftertreatment system

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Ludvig Nilsson; Kim Karlsson; [2018]
    Nyckelord :induction heating; exhaust aftertreatment; nox reduction; Technology and Engineering;

    Sammanfattning : Heavy trucks are commonly powered by combustion engines running on diesel. Since these trucks often run on highways they rarely have to perform cold starts. LÄS MER

  3. 3. Assessment of thermal radiation arithmetic's for jet flames : A study involving generic calculation methods concerning radiation from jet flames with the purpose to determine the safety distance for flame effects

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anne Lee Anderson; [2018]
    Nyckelord :Jet flame; view factor; incident radiation; radiation temperature; safety distance;

    Sammanfattning : Jet flames are commonly used as flame effects in pyrotechnical shows, and are also a possible risk in industries that uses pressurised flammable gas. For these users it is important to  make fire safety engineering calculations to minimise the risks. This project focus on jet flames that are used in pyrotechnic shows where, e.g. LÄS MER

  4. 4. Analysis of Catenary Shaped Timber Structures

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Kristoffer Persson; [2018]
    Nyckelord :Timber construction; Caternary structures; Tensile timber roof; Stress ribbon; Technology and Engineering;

    Sammanfattning : In the design of a building there are many parameters that effect the material efficiency. The choice of structural solution and material are two of the parameters that will be investigated further in this rapport. LÄS MER

  5. 5. Understanding and Modelling Behavioural Requirements: an Exploratory Study

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Marco Trifance; Ivo Vryashkov; [2017-06-22]
    Nyckelord :requirements understanding; requirements modelling; constructive interaction;

    Sammanfattning : Clear understanding of system requirementsis necessary to achieve quality in the architectural designand in the development process of a software system.Several studies focus on the comprehensibility of graphicalmodelling languages. LÄS MER
